ISD1212 Datasheet | Winbond

DESCRIPTION Winbond’s Chip Corder® ISD1200 series provide high-quality, single-chip, Record/Playback solutions to 10- and 12-second messaging applications. The CMOS devices include an on-chip oscillator, microphone preamplifier, automatic gain control, antialiasing filter, smoothing filter, and speaker amplifier. A minimum Record/Playback subsystem can be configured with a microphone, a speaker, several passive ponents, two push buttons, and a power source. Recordings are stored into onchip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through Winbond’s patented Multi-Level Storage (MLS) technology. Voice and audio signals are stored directly into memory in their natural form, providing high-quality, solidstate voice reproduction. 2.
